My 2016 did the exact same thing a few months ago at 56000 miles. Just kept refilling and watching closely. Never a spot or drip in my driveway. Got home one day and coolant dumped out from underneath the passenger side seat. Water pump. Took the dealer they pressure tested and said I had a hairline crack on the drivers side in the radiator. I asked to speak to a manager and insisted they pressure check again. That was not where the big leak was at. They tested again and said yes water pump and radiator. Water pump was 300. They had to special order the radiator and sent me home and told me to keep an eye on the coolant. I used AC Delco cooling system tabs. 7.00 on Amazon. Worked like a charm. It will buy me some time for that 1400 radiator repair.I just sprung a coolant leak on my 2016 Trax at 78000Kms. I haven't been able to locate the leak yet because it's not leaking enough to drip on the pavement. Looking under the hood reveals nothing but I can smell it and the reservoir is dropping ever so slightly. Waiting game, but I will bring it in to get pressure tested.
Post about any issues/problems you have experience with your chevy trax in this thread.
